COOKING-STOVE.

Specification of Letters Patent No. 6,534, dated June 19, 1849.

To all whom t may concern Be it known that I, EBENEZER F.' lNIARrIN, ofRockport, in the county of Essex and State of Massachusetts, haveinvented a new and useful Improvement in the Cooking- Stove; and I dohereby declare that the same is fully described and represented in thefollowing specication and accompanying drawings, letters, figures, andreferences thereof.

Cf the said drawings Figure 1 denotes a top view, Fig. 2, a horizontalsection, and Fig. 3 a central vertical and longitudinal section of myimproved stove. Fig. 4L is a transverse and vertical section takenthrough t-he lire place.

In Figs. 2 and 3 of said drawings A, exhibits the fire place or chamberof combustion. It consists of a close chamber or box, except that it hasa grate a, in the bottom of it, a removable upright grate at one end ofit, and two or more openings c, Z made through its top and for theadmission of fuel. The said lire chamber so made is surrounded on itsfront and -rear sides and one end by a vertical air space e, f, g, the

other end also having an air space h disposed by the side of it, as seenin Figs. 2 and 4. Each of said air spaces has a rectangular opening z'or k, made through the stove plates, and having one or more closingdoors Z or m, a, applied to it. Below the grate a an ash box orreceptacle B, is arranged in the usual manner.

Directly in the rear of the fire chamber and separated from it by thevertical air space g, the oven C is arranged, the said oven being madeto extend from side t-o side of the stove, and to have an opening 0, andclosing door 79, at one or both ends of it as occasion may require. Thesaid oven is separated from the air space g by t-wo vertical slidingdoors D, E, which make part of its front side, and are so arranged as tobe each capable of being drawn outward or laterally through its adjacentside of the stove. When so drawn out whether wholly or partly, they opena communication between the baking space of the oven and the air space gor e, f g. The said space g, is continued underneath the entire bottomof the oven, or opens into a space g, extending directly under the oven.

The flue for discharging t-he smoke and volatile products of combustionis carried directly out of the back and after part of tinuation orextension of the bottom plate of the oven. A discharge pipe a, is led orcarried out of the smo-ke flue space as seen in Figs. 2 and 3. There mayalso be one or more openings or pipes introduced into the back plate ofthe stove, and into the space under the oven, and so arranged as toallow'the hot air of said space to either escape into the apartment inwhich the stove may be, or be led into any other room as occasion mayrequire.

By opening the doors m, n, of the opening 7c, a roasting kitchen o-rapparatus may be set against the opening so as to receive heat from thefront side of the gratey when such may be required. By means of the airspaces c, f, g the space under the oven, and the slide doors D, E, theheat of the two sides and one end of the fire chamber may be thrown intothe oven or under it, and t0 such extent as circumstances may require.lVhen the slides D, E, and the doors m, n, are entirely opened the ovenbecomes a roasting apparatus, made to operate like the ordinary tinkitchen when set up against a fire, the usual objections which resultfrom baking meats, being overcome thereby, and in order to render itmore effective for such purpose, I usually line a part or the whole ofits inside surface with a relect-ing material such as tinned iron orother proper material. The object of the removable grate b is to enablea person to introduce and burn long sticks of wood, in the furnace orfire place, or Such sticks as cannot be conveniently introduced orpassed through the top openings of the said fire place. The top of thefront air space e, I usually puncture with holes or orifices u', c, fw,for the reception of small kettles or pots, which in order to warm theircontents, may be inserted in or over the same, under other-circumstancesthe said holes may have small covers applied to them so as to closethem. By incasing the lire place within an air chamber or space, heatradiated from its external sides .may be carried olf either into theoven,

or into a chimney or Warming-.fines as above specified, so that insummer such heat may be carried off, and not received into the apartmentin which the stove may be, While in Winter it may be introduced into thesaid apartment if desirable.

I lay no claim to the extending of an oven or oven space around a fireot or chamber of combustion so that the heat from the Whole or any partor portions of the external sides of said fire pot or chamber may becommunicated to the air Within the oven;nor do I claim to so connecttheoven by air pipes or otherwise With a space around the fire pot orchamber, and having contrivances to admit cold air from Without, thatair which may pass into and be heated Within said space may be conveyedinto the oven; nor do I claim the invention of carrying the smoke andvolatile products of combustion from the fire place or re pot overaround or against the Whole or any part or portion of an oven, but- WhatI do claim as'my invention, is-

The hereinabove explained combination of the oven with the air space e,f g and fire chamber, by means of the sliding doors as specified, thesame being for the purpose of either enabling a person to make use ofthe oven either for baking or roasting as speciied, or to make use of itfor baking While the roasting is done, in a roasting apparat-us set upagainst the opening 7o, as hereinbefore explained.

In testimony whereof I have hereto set my signature this tenth day ofNovember A. D. 1848.
